BINDER.

SPECIFICATION forming part of Letters Patent No. 570,399, dated October27', 1896.

Application iled November '7, 1895. Serial No. 568,192. (No model.)

Vand State of Illinois, have invented certain new and usefulImprovements in Binders, of which the following is a full, clear, andexact description, and which is fully illustrated in the accompanyingdrawings, which are made a part of this specification, and in which-Figure 1 is a plan view of the binder open, a portion being broken away,the bindingstaples being reduced in number for clearness. Fig. 2 isasectional view, upon alarger scale, on the line 2 2 of Fig. l, thebroken-out parts being restored. Fig. 3 is a detail section, upon thesame scale as Fig. 2, on the line 3 3 of Fig. 1, the broken-out portionsbeing restored. Fig. 4 is a detail end elevation of the binder. Fig. isa perspective of a pack age of sheets adapted to be secured in thebinder, and Fig. 6 is a perspective of a fastening-staple used in thebinder.

The invention relates to means for binding together loose sheets," suchas the successive numbers of newspapers and the like, and its object isto provide a simple and inexpensive binder of this class which will notrequire the use of thread.

The invention consists in lining the back of a book-cover with a stoutstrip, preferably of leather, in which are set series of wire staples,which may be passed through the leaves to be bound and then bent tosecure them.

In carrying out the invention I use a pair of sti boards A A', which arecovered by the pieces c a', of canvas or similar material, one upon eachside, and of sufcient size to cover both boards when the latter arespaced apart a distance corresponding to the desired thickness of thebook, the limp por# tions of the covering material between the twoboards constituting its back. A stout strip B, preferably of leather, issecured to the inside of the book-back by having its edges connected tothe canvas covering c' of the boards, along the edges of the latter.

Vire staples ZJ b are set in this lining, projecting through from itsinner side and having their ends folded down. Two sets of these staplesare used, one located near each end of the strip B, and each set ispreferably arranged in two series b b, as shown, so that they will beless crowded.

The leaves C to be bound Will be folded in the usual manner, and astaple at each end of the strip B, having had its ends raised, will beinserted through them at the crease, and its ends being again turneddown they will be securely and permanently held.

A very pliable and non-elastic wire is used for the staples, so thatthere will be no danger of breaking it in the bending, and so that itsends may be neatly folded down out of the way. While it is not theprimary purpose to provide in this invention a mere temporary binding,it is clear that it may be used for that purpose, the leaves beingeasily removable.

I claim as my invention 1. In a binder, the combination with the boardsA, A', and the flexible back, a, of the lining B, secured Within theback and the wire staples projecting inwardly through the lining, suchstaples being set in series arranged longitudinally as to the back andwith the plane of each staple coinciding with the alinement of itsseries, substantially as described and for the purpose set forth.

2. The combination with a bookcover having a limp back or joint ofstaples secured in the back and having their ends projecting inwardlythrough the inner surface thereof, such staples being set in seriesarranged longitudinally as to the back and with the plane of each staplecoinciding with the alinement of its series, the adjacent members of theseveral series being set staggered, substantially as described and forthe purpose set forth.
